Cabinet with a roll door

ABSTRACT

A cabinet includes two opposite sidewalls and a roll door apparatus. Each sidewall longitudinally defines a number of cutouts. The roll door apparatus includes a first pole rotatably mounted between tops of the sidewalls, a roll door reeled about the first pole. The roll door has a first end mounted to the pole, and a second end opposite to the first end. A fixing piece extends from the second end of the roll door. Opposite ends of the fixing piece are engaged in two of the cutouts of the sidewalls.

BACKGROUND

1. Technical Field

The present disclosure relates to a cabinet.

2. Description of Related Art

Doors of cabinets are generally made of armor plates and mounted to thecabinets with screws, which can be difficult and time-consuming becausethe doors are heavy. Furthermore, in opening a cabinet, the door of thecabinet is generally rotated about one of the sidewalls of the cabinet.A space for the door rotation is needed, which requires additionalspace.

DETAILED DESCRIPTION

The disclosure, including the accompanying drawings, is illustrated byway of example and not by way of limitation. It should be noted thatreferences to “an” or “one” embodiment in this disclosure are notnecessarily to the same embodiment, and such references mean at leastone.

Referring to FIGS. 1 and 2, an exemplary embodiment of a cabinet with aroll door includes a top wall 10, a bottom wall 20, two oppositesidewalls 30 perpendicularly connected between opposite sides of the topand bottom walls 10 and 20, a front board 50 perpendicularly connectedbetween upper portions of front sides of the sidewalls 30, and a rolldoor apparatus 40.

A plate 32 perpendicularly extends from the front side of each sidewall30 toward the other sidewall 30 and longitudinally defines a slide slot320 from top to bottom and facing the other sidewall 30. Each plate 32defines a plurality of cuneiform cutouts 324 (referring to FIG. 7)communicating with the corresponding slide slot 320 in a rear wall 322bounding the slide slot 320. Each sidewall 30 defines two fixing holes(not shown) in tops of front and rear sides of the sidewall 30.

Referring to FIG. 3 to FIG. 5, the roll door apparatus 40 includes afirst pole 44, a second pole 42, two clockwork springs 440, a resilientbelt 460, and a roll door 46.

The clockwork springs 440 fitted about opposite ends of the first pole44. The resilient belt 460 made of rubber or leather. Each clockworkspring 440 includes an inner end 444 mounted to the first pole 44, andan outer end 446 opposite to the inner end 444 and mounted to the topwall 10 or one of the sidewalls 30 to which a corresponding one ofopposite ends of the first pole 44 is pivotably fixed.

Two pins 420 extend out from opposite ends of the second pole 42. Twopins 442 extend out from opposite ends of the first pole 44.

The roll door 46 includes a plurality of main pieces 462 each includingtwo hooks 470 a at a top end and a bottom end of the main piece 462, aplurality of C-shaped connection piece 464 each including two latches472 at top and bottom ends of the connection piece 464, an M-shapedoperation portion 466 forming two hooks 470 b at a top and a bottom endsof the operation portion 466, and a C-shaped engaging portion 468forming a hook 470 c at a top end of the engaging portion 468. Each mainpiece 462 defines a plurality of vents 476. An engaging piece 474extends toward the hook 470 from a bottom end of the engaging portion468 opposite to the top end.

Referring to FIGS. 6 and 7, in assembly, the latches 472 of a firstconnection piece 464 are movably latched with one of the hooks 470 a ofa main piece 462 and one of the hooks 470 b of the operation portion466. The latches 472 of a second connection piece 464 are movablylatched with the other hook 470 b of the operation portion 466 and thehook 470 c of the engaging portion 468. The latches 472 of each of theremaining connection pieces 464 are movably latched with two hooks 470 aof two adjacent main pieces 462. Thereby, a connection piece 464 isconnected between every two adjacent main pieces 462, and the roll door46 capable of being reeled. The resilient belt 460 includes a first endfixed to the first pole 44. The resilient belt 460 is reeled about thefirst pole 44. A second end of the resilient belt 460 opposite to thefirst end is connected to a main piece 462 opposite to the engagingportion 468. The pins 442 are inserted into the front side fixing holesof the sidewalls 30, to pivotably mount the first pole 44 between topsof the front sides of the sidewalls 30. The pins 420 are inserted intothe rear side fixing holes of the sidewalls 30, to pivotably mount thesecond pole 42 between tops of the rear sides of the sidewalls 30. Theroll door 46 is reeled about the first pole 44, and is rounded about thesecond pole 42 from bottom to top. The roll door 46 passes a top of thefirst pole 44 and extends downward. Thereby, opposite sides of a distalend of the roll door 46 opposite to the resilient belt 460 are slidablyreceived in the slide slots 320 of the sidewalls 30. Opposite sides ofthe engaging piece 474 are engaged in two topmost cutouts 324 of thesidewalls 30, to fix the roll door 46 to the sidewalls 30. The frontboard 50 covers the distal end of the roll door 46 (referring to FIG.1).

In use, the engaging portion 468 is pulled away from the rear wall 322,to disengage the engaging piece 474 from the topmost cutouts 324. Theoperation portion 466 is then moved down toward the bottom wall 20, topull down the roll door 46. The clockwork springs 440 and the resilientbelt 460 are deformed. When the cabinet is needed to be partly closed,opposite ends of the engaging piece 474 are correspondingly engaged intwo corresponding cutouts 220 to fix the roll door 46 in a certainheight, such as a middle of the cabinet, as shown in FIG. 2. When thecabinet is needed to be closed completely, the engaging piece 474 isengaged in the lowest cutouts 324.

In opening the cabinet, the engaging portion 468 is pulled away from therear wall 322, to disengage the engaging piece 474 from the cutouts 324.The operation portion 466 is then released, the clockwork springs 440and the resilient belt 460 are restored, thereby, the roll door 46 areautomatically reeled about the first pole 44.

In another embodiment, the second pole 42 may be omitted.

In another embodiment, the resilient belt 460 may be omitted.

In another embodiment, the clockwork springs 440 may be omitted.

In another embodiment, the resilient belt 460 and the second pole 42 maybe omitted.

It is believed that the present embodiments and their advantages will beunderstood from the foregoing description, and various changes may bemade thereto without departing from the spirit and scope of thedescription or sacrificing all of their material advantages, theexamples hereinbefore described merely being exemplary embodiments.
